“Finding these photos is critical for our clients,” said attorney Michael Pfau, whose Seattle-based law firm represents some of the alleged victims. “Hopefully the hospital can do the right thing and accelerate the investigation.”

Archibald, who died in 2007, worked as an endocrinologist specializing in childhood growth. His victims charge the doctor used his position at the hospital to fondle, masturbate and photograph the genitals of his patients – most of them young and male.

Katsikis, asked what should happen to any photos still around from his only appointment with Archibald, offered a quick response.

“It didn’t feel good. The older I got, it always bothered me. But I was 11, and he was a famous doctor.”

Officials at the Upper East Side hospital have acknowledged inappropriate contact with Archibald’s young patients, although they have not said whether any photographs were found during an internal investigation. Lawyers allege dozens of victims were abused by the doctor.

The hospital, where Archibald spent 32 years as a senior physician and university professor, had no comment in advance of a Tuesday news conference regarding the photos.

“I want to help other victims,” said Katsikis. “If I can come out and tell my story, and if I can inspire another victim who is too scared to come forward and to point out a sexual predator that might be hiding in plain sight . . . that is the way to go.”
